• W339929248 abstract "아크릴아마이드의 형성과정에서 가열조건이 아크릴아마이드의 생성량과 아크릴아마이드 형성에 관여 또는 동반 생성하는 화합물을 조사하기 위하여, 아스파라긴과 포도당의 등량 혼합물을 125, 150, 175 및 <TEX>$200^{circ}C$</TEX>에서 각각 10, 20 및 30 분간 가열하는 모델반응을 이용하였다. 가열한 반응물을 ethyl acetate 및 methanol 2종의 용매로 달리 추출하고 FFAP capillary column과 HP-5MS 5% phenyl methyl siloxane column으로 GC/MS에서 분석한 결과, 아크릴아마이드는 methanol추출물을 FFAP capillary column으로 분석한 결과에서 retention time 23.53분에서 검출되었고 최저검출한계는 4 ng 이었다. 아크릴아마이드 생성량은 <TEX>$175^{circ}C$</TEX>보다. 낮은 125 및 <TEX>$150^{circ}C$</TEX>에서는 온도와 가열시간을 증가시킬수록 점차 증가하여, <TEX>$175^{circ}C$</TEX>에서 10분간 처리하였을 때 최대량인 <TEX>$116{mu}g/g$</TEX>을 생성하였지만 175 및 <TEX>$200^{circ}C$</TEX>에서는 온도 및 가열시간을 증가시킬수록 감소하는 결과를 나타내었다. 아크릴아마이드이외 반응생성물들로서, 1,3-dihydroxypropanone, 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyrane-4-one 및 5-hydroxymethylfurfural이 다량으로 검출되었으며, 또 다른 화합물인 5-methylfurfural, 2-acetylpyrrole 및 N,N-dimethylcyclohexamine 등은 소량 생성되었음을 확인하였다. The Formation of acrylamide was studied in Maillard model reaction systems based on asparagine-glucose. The mixture of asparagine and glucose in equal molar ratio, and then heated at 125, 150, 175 and <TEX>$200^{circ}C$</TEX> for 10, 20 and 30 minute, respectively. The reaction products were extracted with ethyl acetate and methanol, and then isolated and detected on FFAP capillary column and HP-5MS 5% phenyl methyl siloxane column by using GC/MS. Acrylamide was detected only from methanol extracts and on FFAP capillary column, at retention time 23.53 min., and the detection limit was 4.6 ng. Acrylamide content mainly increased with increasing temperature and processing time till <TEX>$175^{circ}C$</TEX>, therefore, maximal acrylamide formation occurred at <TEX>$175^{circ}C$</TEX> for 10 minute (<TEX>$116{mu}g/g$</TEX>), while, above <TEX>$175^{circ}C$</TEX>, higher temperatures or prolonged processing times caused a decrease of acrylamide levels, finally disappeared at <TEX>$200^{circ}C$</TEX> for 30 minute. Three major compounds were identified as 1,3-dihydroxypropanone, 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyrane-4-one and 5-hydroxymethylfurfural, and three minor compounds also as 5-methylfurfural, 2-acetylpyrrole and N,N-dimethylcyclohexamine, from ethyl acetate or methanol extracts on FFAP or HP-5MS capillary column." @default.
